Filed July lO, 1935 A Avlis? Patented June 30, 1936 UNITED STATESPA'IENT OFFICE Application `luly 10, 1935, Serial No. 30,613 In GreatBritain April 25, 1935- '1 Claims.

l This'invention relates to safety razors and more specifically to asafety razor having an independent guard plate and meansy for varyingits positionwith regard to the cutting edges of the blade. The object ofthe invention isI to provide a simple and practical form of device forvarying' the space between the edge.v of the blade and the guard so thateither a moderate or a keener shave may be obtained depending upon thenecessities of the case and depending also upon the particularidiosyncrasies of the person being shaved.

Another object ofthe invention is to provide a form'o clamping devicewhich mayy be simpIy sprung into clamping position with the blade inplace by the pressure of a finger', and since in a device with a springclamp the position of the edges of the bladel due to exing is a'fi'xedone, it is found necessary to have some adjustment possible of the guardin relation to the edge of theblade, which it is the aim of this deviceto provide.'

u Other objects of the invention will appear in the followingdescription of the accompanying drawing illustrating preferredembodiments. of

the invention in Wh.ich:-`

Figure 1 is a sectional elevation showing the razor in operativeposition but with the end adjusted at maximum opening;

"Figure 2 is a sectional View 'on the line A-A of Figure l;

Figures 3 to 8 show the several parts of Figure 1' separated, namely:

1 Figure 3 shows a backing plate .and stem;

Figure 4 a spring; i

Figure 5 an independent guard plate Figure 6 the adjusting nut;

Figure 7 the handle and carrier, and

Figure 8 the spring catch;

Figure 9 shows a carrier with pins for guiding same;

Figure 10 shows ,a spring adapted to t the guide pins;

Figure 11 is another form of the independent guard plate;

Figure 12 is an underside view of same bearing a scale by which theadjustment of the guard is regulated.

In order to show the details more clearly Figures 1 to 8 are drawn to anenlarged scale and it should be understood that Figures 9 to 12 areemployed with a similar handle and carrier to that shown in Figure 1,the only variation being in the means for guiding the guard platethereon.

Referring rst to Figures l to 8, I is a handle connected with anauxiliary carrier 2, the handle being provided with a hole 3 into whichis pressed the stem 4 on the backing plate 5 provided, as shown, withguide pins 6 entering holes in the carrier 2. The stern 4 is alsoprovided with a groove I on its inner end and a tapered extrem- 5 ity 8.

Arranged transversely across the handle is the clasp i6' provided with ahole I I and having three prongs I2, L3,- .ti of which' the central oneis tted with a nger disc Iiand the spring I6, the l0 clasp EG beingarranged to slide within the slot I'I in the handle so that the edges ofthe slot are caught by the spring I6,

By inserting the blade 20 between the backing plate 5 and the carrier 2and pressing down the l5 stern the groove 'I will be caught by the endof the clasp I controlled by the spring IS and will be instantaneouslysecured to the carrier with the blade iiexed. i

ProvidedA on the handle I is an' enlargement 2I 20 carrying' a screwthread, and arranged tol engage therewith is the adjusting nut 22.

23 is an independent guard plate provided with the guide pin holes 2'4and a central hole 25 through which the handle is passed before the 25lmounting of the nut 22. The guard plate 23 is also provided at each endwith recesses 26 into which the ends 2l of the carrier 2 t, the leafspring 28 lalso having end lugs which t within the recesses 26, whileits central portion is cut 30 away at 29 to admit both the handle andthe guide pins 6.

It will be seen that the nut 22 is made with a pointer 30 which works inconjunction with a scale suchlas 3 I, ,as shown in Figure 12 where the35 nutis removed but the pointer 3U is shown diagrammatically toindicate the device; it Will be understood that a scale such as 3I ismarked also on the underneath side of the guard plate 23 of Figure 5.

The blade having been placed on the backing plate 5 and the stem groovepushed home until caught by the spring clasp I0, it is rmly secured tothe carrier 2 by the action of the spring I6, being then permanently xedas regards its edges 9, 45 9; before the clasp I0 is mounted in the slotI1 the spring 28 and the guard plate 23 are slid into position with theend of the spring 28 and the end 2'! of the carrier occupying therecesses 26 of the plate 23. Thereafter the nut 22 can be 50 screwed upon the thread 2l without causing the rotation of the plate 23 about thehandle.

On reference to Figure 2 it will be seen that screwing up of the nut 22pushes up the plate 23 so that its guard edges approach nearer to the 55blade edgesl 9, 9, by which means the gap 33 is reduced. I'Ihe reductionof this gap results in a smooth shave whichiis not severe on the skinand wouldbe likely to be used by people with a delicate skin. 2 Y

When a rough shave is required the nut 22 is adjusted inl the oppositedirection and a keener shave is obtainable; the various settings of theraznr gap being -adjfusted according to the scale 3| andthe turning ofthe nut soy that its pointer Sacomes to a particular position on thescale which is found by experience to be the best for Y the particularindividual using the razor.

As will be seen by the markings? Keen and Mediumand the ,accompanyingarrows, adjustment takes place and the scale is marked in accordancewith a clock (for example) so that an operator will iind it easier toremember the position in which to set the adjusting screw.

For removal of a blade it is merely necessary' to press on the lingerdise I5 upon which the spring I6 is mounted, when-the hole I Icentralizes itself inrelation to the end 8 and the backing plate 5 comeslooseffdue to the action of the blade 20 unexing, Y Y

In the device sli-own in Figures 9 to 12,"four pins 34 are used toguidethe guard plate 35. corresponding holes 36 being made therein tosuit the position of the-pins 34, and in this case the end 3'I of ftheguard plate need `not be recessed but may eorrespond to the undersidecurves of the backing plate as shown inFigure 2.

YThe norihal guide pins IiV of the backingY plate wil occupy the holes38, 39 as before. j;

from the preceding Vdescription it will seen tl'rat a simple pressurewith the iinger on the disc I5 immediately releases the blade andsimilair'pressure on the backing plate returnsE it to place.Consequently, replacement or removal for cleaning is attained veryquickly,I arid by means of a device that is not likely to getout oforder, accompanied by means Vfor varying the gap between the blade andtheguard, which is highly importantin a razor of this character.
